Thank you @gichiba for posting the call digest. TeamX is short for Team Enterprise, Cross Shard and Stateless. That was a bit of a mouthful, and ECSS was too, so we went with X. Our team is Sandra Johnson (@sandJohnson), Horacio Mijail (@hmijail), Raghavendra Ramesh (@Raghavendra-PegaSys), Zhenyang Shi (@wcgcyx), and myself, Peter Robinson (@drinkcoffee). David Hyland-Wood (@prototypo) has been temporarily seconded to the team from the ConsenSys / PegaSys Consensus Protocols Team.
We have been working on Ethereum Private Sidechains (an ephemeral on-demand permissioned blockchain technology) and Atomic Crosschain Transactions (https://github.com/PegaSysEng/sidechains-samples/blob/1613533b34cf78f281b2ab1f8a08dc04ca9358a0/AtomicCrosschainTransactions-WhitePaper.pdf). More recently, we have created a few proposals for cross shard techniques (Atomic Cross Shard Function Calls using System Events, Live Parameter Checking, & Contract Locking, Atomic Asynchronous Cross-shard User-level ETH transfers over netted EE transfers, Asynchronous User-level ETH transfers over netted balance approach for EE-level ETH transfers), and proposal for caching in stateless (https://hackmd.io/-_II-qyQR6OOeS8J7gMVgQ?view).
In the Stateless space we are working on:
- Code Merklization and witness compression
- Modelling related to Stateless and witnesses
- Data gathering.
- Networking.
We are also continuing our work on enterprise Ethereum. One area that we will be publishing on soon is a layer 2 cross-blockchain function call approach. This technique will be applicable to Eth2 Cross Shard.
